Objective:To assess the association of -c.108C>T and c. 192Q>R polymorphisms of paraoxonase 1 ( PON1) gene with preeclampsia (PE) and the influence of genotypes on the metabolic and oxidative stress indexes among Chinese women. Methods:This case-control study has included 334 patients with PE and 1337 healthy pregnant women. The -c.108C>T and c. 192Q>R genotypes were determined by PCR and restriction fragment length polymorphism method. Metabolic and oxidative stress parameters were also analyzed.Results:No statistical difference in the genotypic and allelic frequencies for the -c.108C>T and c. 192Q>R polymorphisms of the PON1 gene was found between the PE patients and the healthy controls ( P>0.05). Nevertheless, the 192Q-108T haplotype of these polymorphisms was associated with an increased risk of PE ( P = 0.007). Total antioxidant capacity(TAC)and atherosderosis index were higher in patients with the -108TT genotype compared with those with a CT genotype ( P < 0.05); whilst total oxidant status was lower in patients with a CT genotype compared with those with a CC genotype ( P = 0.036). Malondialdehyde level was higher in patients with a 192RR genotype compared with those with a QQ genotype ( P = 0.019). TAC level was higher in patients with a RR genotype compared with those with a QR genotype ( P = 0.015). Conclusion:The 192Q-108T haplotype of the PON1 gene is associated with the risk for PE. These polymorphisms may be associated with abnormal lipid metabolism and oxidative stress among Chinese PE patients.

Objective Observing the feasibility of acute endovascular treatment for patients with symptomatic anterior intracranial atherosclerotic severe stenosis.Method From Jun 2019 to Jun 2023,30 symptomatic anterior intracranial atherosclerotic severe stenosis cases were retrospectively collected in the Guangdong Hospital of Traditional Chinese Medicine to evaluate the risk stratification score and explore the safety and effectiveness of acute(≤72.0h)endovascular treatment.Endovascular treatment includes balloon dilation+self-expanding stent placement,balloon-mounted stent placement,and balloon dilation.From the clinical experience,the risk stratification score was based on the ABCD3-I score for transient ischemic attacks(TIA)and additional evaluation of cerebral watershed infarction to identify the risk of stroke progression or recurrence in acute stage of symptomatic intracranial artery stenosis.The score of 0-3 was defined as low-risk,4-7 as medium risk,and 8-13 as high-risk.The successful revascularization of blood flow is determined based on the residual stenosis≤50％and the extended thrombolysis in cerebral infarction(eTICI)＞2c.The information of patient receiving endovascular treatment was recorded,including age,sex,risk factors of cerebrovascular disease(hypertension,diabetes,hyperlipidemia,hyperhomocysteinemia,drinking history,smoking history),onset data(time from onset to endovascular treatment,symptoms,progression),diseased vessels,risk stratification score,National Institutes of Health Stroke Scale(NIHSS)score before and 90 days after surgery,modified Rankin scale(mRS)score 90 days after surgery,intraoperative cerebrovascular events(intracranial hemorrhage,occlusion of responsible vessels),and postoperative cerebrovascular events 90 days after surgery(intracranial hemorrhage,cerebral infarction,TIA and in-stent restenosis)and deaths.Results Among 30 patients with symptomatic anterior intracranial atherosclerotic severe stenosis,3 patients were excluded from the time interval between onset and endovascular treatment＞72.0 hours,1 patient needed long-term anticoagulant drugs due to other diseases,1 patient lost follow-up,3 patients coexisted with other cardiogenic cerebral embolism diseases,4 patients with non-atherosclerotic arterial stenosis,and 7 patients refused emergency endovascular treatment.11 patients were finally included.(1)All 11 patients were successfully treated with endovascular treatment,and 7 were males;age ranged from 52 to 76 years old,with a median age of 64 years old;there were 9 cases with hypertension,3 cases diabetes,7 cases hyperlipidemia,2 cases hyperhomocysteinemia(only 9cases performed the examination),2cases smoking history,1 case drinking history;time from onset to endovascular treatment is 4.0-72.0 h,with a median time of 12.0 h;there were 3 and 8 cases of infarction in the left and right hemispheres,respectively,with 4,3,and 2 cases accompanied with anterior-posterior watershed,medial watershed,and anlerior-medial-posterior watershed infarctions,and 1 case accompanied by posterior-medial,anterior-medial watershed infarctions.(2)Among the 1 1 patients,the risk stratification score was 10-13 points,with a median score of 11 points;preoperative NIHSS score ranged 0-11 points,with a median score of 7 points.(3)Among the 1 1 patients,10 lesions located in the middle cerebral artery and 1 in the C7 segment of the internal carotid artery;the preoperative stenosis rate was 70％to 99％,with a median stenosis rate of 86％;preoperative eTICI grading was 2a in 7 cases and 2b50 in 4 cases(with slow distal blood flow);9 cases received balloon dilation and self-expanding stent placement,1 case received balloon-mounted stent placement,and 1 case received balloon dilation treatment;the postoperative stenosis rate is 10％to 20％,with a median stenosis rate of 15％;there were 3 cases with postoperative eTICI grade 2c and 8 cases with grade 3.(4)Among the 11 patients,one experienced intracranial hemorrhage on the first day after surgery and one had a new cerebral infarction on the third day after surgery.Eight patients were followed up by imaging 90days after surgery,demonstrating 2 cases of in-stent restenosis;90 days post-surgery,NIHSS score was 0-20 points,with a median score of 2 points;after 90 days of surgery,the mRS score was 0-4 points,with a median score of 1 point.There were 8 patients with mRS score ≤ 2 and no death events occurred.Conclusions Preliminary analysis shows that acute endovascular treatment for symptomatic anterior intracranial atherosclerotic severe stenosis has certain effectiveness,but the safety needs to be further validated.The screening of high-risk patients using risk stratification scores still requires further exploration through large sample and multicenter studies.

Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.

Objective: To understand the epidemiological characteristics of bacillary dysentery with multiple-onset in Henan province from 2005 to 2020. Methods: The reported cases of bacillary dysentery (including confirmed cases and clinically diagnosed cases) in Henan Province from January 2005 to December 2020 were collected through China's National Disease Supervision Information Management System. The main information included gender, age, home address, date of onset and date of diagnosis. The interval between two episodes of the same case was more than 15 days, which was judged as two episodes. The incidence characteristics of bacillary dysentery patients with two or more cases in Henan Province from 2005 to 2020 were analyzed, and the regional distribution map of cases was drawn using ArcGIS software. Results: From 2005 to 2020, a total of 250 430 cases of bacillary dysentery were reported in Henan Province, with a cumulative incidence rate of 228.66/100 000. There were 2 342 cases with two or more attacks. The incidence of recurrent cases of bacillary dysentery increased year by year (χ²_trend=2 932.28, P<0.001). There was no significant difference in the incidence of two or more cases of different sexes (χ²=0.39, P=0.540). There was significant difference in the incidence among different age groups (χ²=438.40, P<0.001). The incidence of two or more cases in the 60-69 age group was relatively high (1.70%). The shortest time interval between the onset of the disease was 16 days, and the longest was 5 579 days, with M (Q₁, Q₃) about 428 (237, 843) days. Compared with healthy people, those with a history of bacterial diseases had a higher risk of developing bacillary dysentery (RR: 4.12, 95%CI: 3.95‒4.29). Conclusion: The proportion of patients with multiple-onset shows an increasing trend, and there is an age difference.

OBJECTIVE: To compare the completion time of endotracheal intubation and laryngeal mask implantation in operating room and on slope of ski resort, and to discuss the optimal method of estab-lishing artificial airway on slope of ski resort. METHODS: The simulator was placed with the head under the feet on slope of ski resort. The artificial airway was established by tracheal intubation assisted by video laryngoscope (endotracheal intubation group) and laryngeal mask placement (laryngeal mask group) respectively by an anesthesiologist who wore full set of ski suits, helmets, goggles, gloves and ski boots. Each method was repeated 5 times, and the operation time of artificial airway establishment was recorded. While the simulated human was placed flat on the operating table in an operating room of a hospital, and the artificial airway was established by the same anesthesiologist using the same methods. Time was recorded and repeated for 5 times. The completion time of endotracheal intubation and laryngeal mask placement in the operating room and on the ski slope were compared. RESULTS: The operating time of tracheal intubation in the operating room was longer than that of laryngeal mask placement [(79.8±10.4) s vs. (53.4±2.7) s, P=0.005], and the operating time of endotracheal intubation on the ski slope was longer than that of laryngeal mask placement [(209.2±32.7) s vs. (72.2±3.1) s, P=0.001]. The time of endotracheal intubation group on the slope of the ski resort was longer than that in the opera-ting room(t=-7.851, P=0.001). The time of laryngeal mask group on the slope was longer than that in the operating room (t=-19.391, P < 0.001). CONCLUSION On ski slope, both of tracheal intubation assisted by video laryngoscope and laryngeal mask placement can quickly complete the establishment of artificial airway, but the time required is longer than that in the operating room. The time of laryngeal mask placement to establish artificial airway is shorter than that of tracheal intubation assisted video laryngoscope, which may have a certain advantage in ski rescue.

A contributory role of oxidative stress and protection by antioxidant nutrients have been suspected in cataract formation. Ganoderic acid A (GAA), an effective lanostane triterpene, is widely reported as an antioxidant. The aim of this study is to investigate the potential effects of GAA on cataract formation. After lens epithelial cells (LECs) were exposed to UVB radiation for different periods, cell viability, apoptosis-related protein levels, malondialdehyde (MDA) and superoxide dismutase (SOD) activities were monitored. We found that cell viability, the Bcl-2/Bax ratio and SOD activity were increased, while Cleaved caspase-3 levels and MDA activity were decreased compared with those in UVB-impaired LECs after GAA treated. Furthermore, GAA activated PI3K/AKT in UVB-impaired LECs and effectively delayed the occurrence of lens opacity in vitro. In conclusion, these findings demonstrated that GAA exhibited protective functions in SRA01/04 cells and rat lenses against UVB-evoked impairment through elevating cell viability and antioxidant activity, inhibiting cell apoptosis, activating the PI3K/AKT pathway and delaying lens opacity.

OBJECTIVE: To assess the association of apolipoprotein (apo) C1 (APOC1) gene rs4420638A/G and -317H1/H2 polymorphisms with the risk of pre-eclampsia (PE) and the influence of their genotypes on the clinical and metabolic indexes among Chinese women. METHODS: In total 289 PE patients and 824 women with uncomplicated pregnancies were included. The rs4420638A/G genotype was determined by a Taqman real-time PCR allelic discrimination assay. The -317H1/H2 genotype was measured through PCR and restriction fragment length polymorphism analysis. Serum lipid and apo levels were measured by an enzymatic kit and a PEG-enhanced immunoturbidimetric assay. RESULTS: Allelic and genotypic frequencies of the APOC1 gene rs4420638A/G and -317H1/H2 were not significantly different between the two groups (all P> 0.05). However, patients carrying the G allele of the rs4420638A/G locus had higher serum levels of triglyceride, non-HDL-C and apoB, and a higher apoB/apoA1 ratio compared with those with an AA genotype (all P< 0.05). Patients carrying the H2 allele of the -317H1/H2 polymorphism had smaller delivery gestational weeks compared with those with the H1H1 genotype (P< 0.05). CONCLUSION Polymorphisms of the APOC1 gene rs4420638 and -317H1/H2 sites may be associated with abnormal lipoprotein metabolism among Chinese patients with PE, though no association was found between variants of the APOC1 gene and the risk of PE among them.

OBJECTIVETo investigate effects of GSTM1 and GSTT1 gene polymorphisms on serum lipid and apopoprotein levels in healthy normolipidemic and endogenous hypertriglyceridemic subjects.

METHODSTwo hundred and thirty-seven healthy normolipidemic and 102 endogenous hypertriglyceridemic subjects from a population of Chinese Han nationality in Chengdu area were studied using the multiplex polymerase chain reaction (PCR). Serum lipids were measured by enzymatic kits and apolipoproteins AⅠ, AⅡ, B100, CⅡ, CⅢ and E were measured by the RID kits.

RESULTSThe non-null and null genotype frequencies for GSTM1 site were 39.2% and 60.8% in the control group, respectively, and 47.6% and 52.4% in the HTG group, respectively. The non-null and null genotype frequencies for GSTT1 site were 51.5% and 48.5% in the control group, respectively, and 57.3% and 42.7% in the HTG group, respectively. The GSTM1 and GSTT1 genotype frequencies in HTG subjects were not different from those in the controls, respectively (P>0.05). However, in control group subjects with both null genotypes (GSTT1- and GSTM1-) showed the lowest plasma HDL-C levels (1.29±0.30 mmol/L), whereas those with each of the other three genotype combinations showed relatively higher HDL-C levels. There was significant difference of HDL-C levels between subjects with GSTT1-/GSTM1-and those with GSTT1+/GSTM1-(P<0.05). Similar result was not observed in HTG group. No significant changes of lipid and lipoprotein levels were observed in either GSTM1 or GSTT1 polymorphism alone in control or HTG group.

CONCLUSIONThe present study provides an evidence that the presence of double deletion genotypes is associated with low HDL-cholesterol levels in normal Chinese subjects. However, these polymorphisms are not associated with lipid levels in endogenous hypertriglyceridemia in Chinese population of Chengdu area.

Erectile dysfunction (ED) associated with type 2 diabetes is a severe problem that requires effective treatment. Pancreatic kininogenase (PK) has the potential to improve the erectile function of ED patients. This study aims to investigate the effect of PK on erectile function in streptozotocin-induced type 2 diabetic ED rats. To achieve this goal, we divided male Sprague-Dawley rats into five groups. One group was not treated, and the other four groups were treated with saline, sildenafil, PK or sildenafil, and PK, respectively, for 4 weeks after the induction of type 2 diabetic ED. Then, intracavernous pressure under cavernous nerve stimulation was measured, and penile tissue was collected for further study. Endothelial nitric oxide synthase levels, smooth muscle content, endothelium content, cyclic guanosine monophosphate (cGMP) levels in the corpus cavernosum, and neuronal nitric oxide synthase levels in the dorsal penile nerve were measured. Improved erectile function and endothelium and smooth muscle content in the corpus cavernosum were observed in diabetic ED rats. When treating diabetic ED rats with PK and sildenafil at the same time, a better therapeutic effect was achieved. These data demonstrate that intraperitoneal injection of PK can improve erectile function in a rat model of type 2 diabetic ED. With further research on specific mechanisms of erectile function improvement, PK may become a novel treatment for diabetic ED.
